ICV2 is useless in the argument because Paizo sell most of their products through their online store. I've seen this argument used before and it doesn't apply here.
I am also pretty sure WoTc don't have a breakdown of each product and what it is making. You more than likely will be seeing one number which will most likely reflect everything as a whole. I bet that Magic makes up 95% of those figures.
Are you arguing you think Pathfinder is outselling 5e right now?
